Sona, Aura Version
This is just an idea on changing Sona back to an Aura based champion but with some high skill around choice making. Just some thoughts in my head and figured I would share and get folk's reaction to. This doesn't really have anything to do with if she is balance or not, it just an idea to make her more fun to play while keeping her identity (and probably improving it). She is still using the snuggle zones but there is more reward for using them now and it makes you have to choose which one to have when. I love feedback, not hate.
Passive AURA: Sona's basic abilities each generate a unique aura for 3 seconds that empowers her and all allied champions who enter its radius, also incurring a 0.5-second period during which she cannot cast her other basic abilities. Each aura's duration is extended by 1 seconds for each allied champion it empowers, up to a maximum of 7 seconds.
POWER CHORD: After casting 3 basic abilities, Sona's next basic attack deals「 13 - 192 」(+ 20% AP) bonus magic damage, with an additional effect depending on the last basic ability cast.
